Django Update View Without Slug in the URL
Today I wanted to use the Django Class Based View (CBV) UpdateView but
without a slug identifier in the URL. For example, instead of
/profiles/pydanny/ I would go to
/my-crazy-profile/. Also, I needed
to force authentication.
I've done this with Django functional views a few times times, but today I did it in Django. This is what I did:
1. Added django-braces to my project
Kenneth Love and Chris Jones' awesome django-braces package has some very handy mixins for working with Django CBVs. Kenneth and Chris really understand CBVs, specifically on how to extend them, and have provided a bunch of really useful utility methods in the django-braces library. Yeah, I could figure this stuff out on my own, but since those guys already did the hard work I might as well just lean on them.
pip install django-braces==0.1.3
INSTALLED_APPS = (
2. Wrote the view
Assuming a very simple profile Model and Form (which they weren't - but that's not what this post is about), this is how I implemented the view:
from django.views.generic import UpdateView
from braces.views import LoginRequiredMixin # handles authentication
from profiles.forms import ProfileForm
from profiles.models import Profile
class ProfileUpdateView(LoginRequiredMixin, UpdateView):
form_class = ProfileForm
success_url = "/my-crazy-profile/" # You should be using reverse here
3. Wrote the URLconf
The URL pretty much wrote itself:
from django.conf.urls.defaults import patterns, url
from profiles import views
urlpatterns = patterns("",
For a while, I've used django-braces for anything that involves CBVs. I
can't imagine working on projects using CBVs without them. In fact,
some of the mixins such as
LoginRequiredMixin are things that I could
argue ought to be in core Django.
This pattern really nails the sweet spot of Django CBVs. Thanks to the use of mixins and model forms, I get an amazing amount of stuff done in a 5 line CBV.
